AF QQHQQ Suva "to:

s Be it known that 'I',{E'i ;w.sT'Wom, a citizen of'ithe United States',-"residing at Supefollowing is a'specification.

concern;-

rior, in the county of fDouglas and State-of Wisconsin, have invented, new and useful Improvements in- Hatchwajs, of which the This inventionrelates 'to hatchways for vessels, and has for one ofits objects to provide-a hatchway and hatch which is of substantial and durable construction, com-- aratively easy and inexpensive to manuacture, and-perfectly weather-tight.

Another ob]ect of the invention is the provision of a hatchway in which the hatch is made of two sections which open outwardly in opposite directions by means of a novel mechanism.

A further object of the invention is the employment oftracks extending from opposite sides of the hatchway, on whichthe hatch sections slide during the openin and closing movements, the hatch sections eing supported at their inner portions by' a bar extending across the hatchway and on which rollers carried by the hatch sections move.

An additional object is to rovide a hatchway having a coamingprovi ed with an out-. wardly-extending peri heral flange under which engages inward .-extending flanges on the hatch sections the last-mentioned flanges being adapted to impinge-on a r'ubher or other packing extending entirely around the coaming, whereby -a weather-.

tight joint is provided:'

With these objects in view and others,

will appear-as the description proceeds, the

inventlon comprises the various novel features of construction and arrangement of parts which will be more fully described hereinafter and set forth with particularityin the claims appended hereto. In the accompanying drawings, which illustrate one of the embodiments of the invention, Figure l is a plan view of the improved hatcl way with the hatch sections in. closed position.

Referrin' to the drawing, A designates the deck. 0 'the vessel onwhich is-laid and secured the --base-plate 1 of sheet metal of suitable gage and extending entirely around the hatchway. The hatchway B is provided with a coaming C composed of side members 2 of channel iron, as shown in 3, and end members havingfoutwardly extending flanges 5 disposed flush with the. laterally- ,extending'fianges" or webs 6 of the channel irons 2. "The channel irons 2 are bolted or otherwise suitably secured to the plate 1 and are arranged along the side ed es of the opening 7 of the said plate, Whll'e the end members 4 of the coaming extend into the hatchway and bear against the beams 8 of the deck, Fig. 2.

Arranged inside the hatchway and disposed along .the end members 4 of the coaming are cross-pieces or beams 9, and extending longitudinally of the hatchway and secured to the deck are beams 10. Riveted to the center of one of the beams 10 is a swing-' ing bar 11 fulcrumed at 12 and adapted to hear at its free end on the opposite beam 10 tosupport the hatch sections when the hatchway 1s closed, the said bar being adapted to swln to one side andrest on the beam to wine it is. pivoted when it IS deslred to lower or raise objects into and from the hold of the vessel. 7 g The hatch D is composedof two sectlons '13 which meet at their inner edges-and are r ada ted to slide laterally to opposite sides of the atchway whenit is desired to open the latter.

ofs'uitable gage and has its outer longitudi- Each section is made of sheet metal nal and end edges bent. downwardly and iniwardly to 'form flanges 1 1 to embrace the 'flanges v5- and'fl of the hatchway coaming C,

and around the coaming extends a packing strip 15 ofrubber or other suitable material against which the flanges 14 of the hatch sections bear so as to form a weather-tight joint, the packing strip being disposed under the flanges 5 and 6 of the coaming so as to be held in place thereby.

As shown in Fig. 3,the inner edge of one section is bent into an upwardly-extending flange 16, while the other section is bent into a flange 17 parallel with the other and provided with ahorizontal flange or. cap strip 18 thatextends over the flange 16 'so as to tions and are each provided with rollers 23 that ride on the end cross pieces or beams 9 and with a central roller 24 that rides on the pivoted cross arched to draw the flanges 14 upwardly against the flanges 5 and '6 of the 'coaming.

The hatch sections are stiffened by means of rib pieces 25 arranged tr'ansverselythere: to and riveted or otherwise fastened. Secured to the outer ends of the rib pieces are runners 26 that extend utwardly anddownwardly and are composed of members 27 that span tracks 28 secured to the plate 1 at opposite sides of the hatchway. Each track is of T-shaped cross section as shown in Fig.

5, and the lower ends of the members 27 are bent inwardly toward each other to engage under the oppositely-extending webs 29 ofthe rail and secured to the runner 26 is a roller 30 disposed between the members 27 and arranged to ride over the top surface of the rail and to cooperate with the inturned extremities 31 of the members 27 to connect the levers with the rails.

As the hatch sections move open and closed, they are supported on the tracks 28 by means of the runners 27 and on the ledges 9 and cross bar 11 by the rollers 23 and 24, the rollers permitting the hatch to be opened and closed freely.

In the present instance, separate mechanisms E are employed at opposite ends of the hatchway for manually opening the hatch. Each mechanism comprises a frame 32 bolted or otherwise secured to the supporting plate 1 and mountedin the frame is a horizontal operating screw 33 provided with right and left threads whereby the rotation I of the screw will move the hatch sections inwardly or outwardly simultaneously. On one end of the screw is a gear wheel 34 that meshes with a pinion 35 on a shaft 36 mounted in the frame 32 and disposed parallel with the screw.

The shaft 36 is equipped with an operat ing crank 37, whereby the screw is turned.

On the ends-of each hatch section are In 38, as shown in Fig. 2, to which are hinged y connected members 39 that are threaded to receive the operating screws 33. These members 39 are provided with openings 40 for recelving the shafts 36 whereby the latter rovided with a longitudi-- ate 19 disposed inwardly hatch sections and the opening and closing mechanisms so that the parts will not bind.

bar 11 which is slightly that the apparatus shown is merely illustraserve as guides for the members so that they will not bind on the screws, and the hinge joint 41 between the lugs 38 and members 39 provide freedom of movement between the In opening or closing the hatch, it requires the service of two men to operate both mechanisms E at the same time.

In Fig. 6, a. modification is shown wherein the coaming C is provided with lugs 42 for receiving strips of wood 43 for holding packing strips 44 against the coaming, the strips 43 being secured in place by wedges 45.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of o eration will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention, together with the apparatus which I now consider to be the best embodiment thereof, I desire to have it understood tive, and that such changes may be made when desired, as are within the scope of the claims appended hereto.
